Large parts of this manual originate from Travis E. Oliphant’s book
Guide to Numpy (which generously entered
Public Domain in August 2008). The reference documentation for many of
the functions are written by numerous contributors and developers of
Numpy, both prior to and during the
Numpy Documentation Marathon.

Please help to improve NumPy’s documentation! Instructions on how to
join the ongoing documentation marathon can be found
